Re: Two injured after the tail cone of a MD-83 fell on ground

Usually when an MD80 tail one is dropped it cracks, so it may not be a simple case of re-installing it.

Re: CFM Engine High Oil Consumption

Calculating oil consumption is critical to ETOPs. In order to do so properly, you must assume the oil was serviced properly before. If no oil was added for the prior leg, and was entered as serviced when it wasn’t, then at the end of the next leg, oil would be added for both legs, but the flight tim...
